    摘要: An optical connection module attaches an active or passive optical component to a substrate and aligns the optical component with a first laser. The optical connection module includes a fiber submount that is attached to the substrate and that includes a thermally insulating material having a thickness greater than 20 micrometers. The optical component is soldered to the fiber submount using heat from a second laser. A laser submount is attached to the substrate. The first laser is attached to the laser submount. A fiber bonding pad is located between the thermally insulating material and the optical component. The thermally insulating material and the fiber bonding pad promote lateral heat transfer and limit vertical heat transfer to the substrate during soldering. The thermally insulating material can be integrally formed in the substrate by flame hydrolysis or by anodic bonding.

    摘要: A semiconductor laser unit includes a semiconductor laser device, a first temperature detector that detects a temperature in the vicinity of the semiconductor laser device, and an electronic cooler that heats or cools the semiconductor laser device. The semiconductor laser unit also includes first and second branching devices for extracting first and second branched lights from an oscillation light outgoing from the semiconductor laser device, a band pass filter that transmits only a light of a predetermined wavelength band among the first branched light, and an optical filter that transmits the second branched light so that a transmission loss is increased or decreased in one way with a change of the wavelength within a wavelength band where the oscillation wavelength of the semiconductor laser device can be changed, to output a second monitor light. The levels of lights which transmit each wavelength are transmitted are detected, respectively, and when the level of light that passes through the band pass filter is increased, a direction of changing the wavelength is detected according to an increase or decrease of the level of light that passes through the optical filter, and the temperature is changed by the electronic cooler to control the wavelength of the semiconductor laser device. Thus, both of the output level and the wavelength of the oscillation light from the semiconductor laser are stabilized.

    摘要: A semiconductor laser source having a laser diode and a fiber Bragg grating is described. The laser diode has first and second facets from which output light is emitted. A first end of the fiber Bragg grating is located near the second facet to receive output light from the laser diode. The fiber Bragg grating has a very narrow linewidth about a selected wavelength and reflects output light in the selected narrow linewidth back into the laser diode through its second facet. The output light emitted from the first facet has a very narrow linewidth about the selected linewidth.

    摘要: To provide a laser oscillator allowing the use of a plastic lens in a semiconductor laser module for a high-output laser oscillator while being unlikely to reduce the efficiency of coupling to an optical fiber even if a laser output changes. A laser oscillator comprises a semiconductor laser module with multiple semiconductor laser elements. The laser oscillator comprises: multiple lenses in a first group provided in the semiconductor laser module for causing laser beams from the semiconductor laser elements to pass through; and a lens in a second group provided in the semiconductor laser module for causing all beams having passed through the multiple lenses in the first group to pass through. The lenses in the first group are plastic lenses. The lens in the second group is a glass lens.
